To all whom, it may 30mm.-

Be it lmown that I, JOHN T. CoLLINs, .acitizen of the United States,resi at Hartford, ,in the county of. Hartford. an State of Connecticut,have invented a new and useful;

Mowing-Machine, of which the following is a specification. v Thisinvention relates to a machine which is designed for mowing park andresidence lawns of the motor-propelled type.

The object of this mvention is to provide a mower of this class withsimple steering and adjusting means .whereby the driver can 1 easily andquickly without sto ping the ma:- chine change the direction 0 the cut,the width of the cut, and the relation of the cut.

to the path of travel of the machine.

The accompanying drawings illustrate the steering and. cuttingmechanisms of a machine of this type.

Figure 1 shows a sideelevation of these mechanisms. Fig. 2 shows 8. Ianof the front truck with the cutters an roller, the

section "being taken on the plane indicated by the line-2 2 on Fig. 1.Fig. 3 shows on larger scale a plan of a portion of the cutter.-adjust.ing inions and racks, the section being taken" on t e planeindicated bythe line 3 3 on Fig.

1. Fig. 4 shows an edge view of the cutteradjusting'racks, the sectionbeing taken on the plane indicated by the line 4 4 on Fi 3. Fi 5 shows avertical section on the p ane in icated by the line 5 5 of Fig. 3, andFig. 6 shows side and top views of a hinged joint that may be used inthe connection between cutters and the cutter-adjusting bars.

Any suitable form of motor may be em: loyed for driving this machine. Atthe front end of the tubular frame 6, which supportsthe motor, is a'latform 7. The ear 8,

rojecting upwardly Bular truckame 9, is hinged to the forked lower endof the king-bolt 10, that extends through the platform. The king-bolt isarranged so that the truck may be oscillated on a vertical axis, and thehinge-bolt 39 is arranged so that the truck may oscillate on ahorizontal axis. The truck is supported by a roller 11, that is formedin sections and extends transversely of the machine.

Fastened to the platform is a seat 12 for the driver, and in front ofthe seat is a steering-post 13, through which extends the steering-shaft14, that has a steering-wheel 15 within convenient reach of the .driveroccupying the seat. In a casing on the platform .is keyed to the u omthe top of the t1'1- and keyed to the lower end of the steeringshaft isa pinion 16, that meshes with a inion 17, which is in mesh with the car18, t at per end of the g-bolt, so

that y turning -t e hand-wheel the truck can be turned in eitherdirection for guiding the machine.

Fastened to the sides of and extending forwardly from the truck is aframe 19. This frame holdstwo bars 20. These bars are capable ofmovement horizontally in the frame, and their inner ends, whichoverlap,- one lying above the other, on their front edges, haverack-teeth 21.

Attached to the truck and supported by the rojecting frame is a bracket.22. This brac et supports a tubular shaft 23, through which extends asolid shaft 24. The former has a hand-wheel 25 and the latter ahandwheel 26 within reach of the driver. On the lower end of the shaft23 in a case 27 is a pinion 28, the teeth of which mesh with therackteeth of the u per bar 20, and on the lower end of the sha 24 in thesame case is a pinion 29, the teeth of which meshwith the rackteeth ofthe lower bar 20. By turning one wheel one bar can be moved in or out.transversely of the machine, and by turning, the

other wheel the other bar can be moved in or out transversely of themachine.

Secured to the outer ends of the adjustable bars are yokes 30. Theseyokes. are so secured that they move in and out with the bars, but theiare jointed, preferabl as at 31, in order t at either side may osci lateu and down, so that the yokes may rise an fall and tilt. Attached to theforward end of each of these okes is a mower, which preferably has sideriving-wheels 32, a roller 33,

coact with a fixed blade for cutting.

Fastened to the truck, so as to project for.- wardly at the middle, is ayoke 35. This yokeis referably jointed, so that it may rise and all andtilt, the same as the others. Supported b the forward ends of this yokebetween an back of the other mowers is a mower having driving-wheels 36,a roller 37, and a spiral revoluble cutter 38,.arranged to .coact with afixed blade for cutting.

and a spiral revoluble'cutter 34, arranged to When this machine isrunning, the driver 1 sitting on the seat by means of the handle 15turns the truck, together with the frame and fixed rear and adjustableforward mowers, in any direction which he desires to go. The driverdetermines the width of the swath to the other being left 1n.

pitches and be cut by turning the hand-wheels and 26 and causing theforward outside mowers to be drawn in or pushed out, as desired. If theswath is to be cut on one side of the machine, but one of the mowers ismoved out,

Either of the mow ers may be moved out and the other left in for thepurpose of cutting on one side or the other of the machine, or of courseboth may be moved out for cutting a wide swath or in for cutting anarrow swath. The rear middle mower cuts outside mowers and the rollerback of the mowers which supports the truck rolls the ground after thecut. The truck as a whole oscillates, so as to accommodate itself tounevennesses, and each slde of each mower can rise and fallindependently of the other.

The invention claimed is 1. A self-propelled mower having a roller, atruck supported by the roller, a platform swiveled to the truck, a seatmounted on the platform, steering mechanism carried by the platformadjacent to the seat, transverselymovable bars carried by the truck,revoluble cutters connected with the bars, racks on the bars, pinionsmeshing with. the racks, and hand-wheels carried by the truck adjacentto the seat for turning the pinions, substantially asspecified.

2. A self-propelled mower having a roller, a truck supported by theroller, a platform swiveledto the truck, a seat mounted on the platform,steering mechanism carried by the platform adjacent to the seat, arevoluble cutter connected Withthe truck in front of the roller,transversely-movable bars carried by the truck, revoluble cuttersconnected,

the swath between the two with the bars, racks on the bars, pinions meswith the racks, and hand-wheels carried the truck adjacent to the seatfor turning t e pinions, substantially as specified.

3. A self-propelled mower having a roller, a truck supported by the.roller, a platform swiveled to the truck, a seat-mounted on theplatform, stee platform, a revo uble cutter hinged to the truck in frontof the center of the roller, rev-,

oluble cutters hinged to. the truck on each side of and in front of thecentral cutter, and

'meansfor moving either one or the other of the forward cutterstransversely with relation to the line of travel of the roller,substantially as specified.

4. A self-propelled mower having a roller, a truck supported by theroller, a platform swiveled to the truck, a seat mountedon the platform,a steering mechanism carried by the platform, two bars provided withracks carried by the truck, a pinion meshing with each rack, ahand-wheel carried by the truck mechanism carried by the for turningeach pinion, a revoluble cutter hing-(11. to each rack-bar, and arevoluble cut gierd ged tothe truck, substantially as specie a two barsprovided with-racks carried by the truck, a revoluble cutter hinged toeach rackbar, apinion meshing with each rack, a shaft connected witheach pinion, one shaft extending through the 'other, and a' handwheelconnected with each shaft, substantially as specified.
